Fluvial Processes
Group: 4 #group-4
Relations
- Floodplains: Floodplains are flat areas adjacent to rivers, formed by deposition during floods.
- Braided Streams: Braided streams are streams that divide and rejoin around sediment deposits, common in valley floors.
- Downcutting: Downcutting is the vertical erosion of a stream channel, deepening the valley over time.
- Alluvial Plains: Alluvial plains are flat areas formed by the deposition of sediment from rivers and streams.
- Alluvial Fans: Alluvial fans are fan-shaped deposits of sediment formed where a stream exits a valley.
- Lateral Erosion: Lateral erosion is the sideways erosion of valley walls, widening the valley over time.
- Canyons: Deep, narrow valleys with steep sides are called canyons, often formed by fluvial erosion.
- Gorges: Gorges are deep valleys with very steep, rocky sides, often formed by fluvial erosion.
- Deposition: Deposition is the process by which sediment is deposited by streams, forming features like floodplains and deltas.
- Valley Formation: The action of rivers and streams, including downcutting, lateral erosion, and sediment transport, plays a major role in valley formation.
- Fold Valley: Fluvial processes, such as erosion by rivers and streams, can also contribute to the formation and evolution of fold valleys.
- Sediment Transport: Streams transport sediment eroded from upstream, contributing to valley formation and deposition.
- Oxbow Lakes: Oxbow lakes are curved lakes formed when a meander is cut off from the main river channel.
- Headward Erosion: Headward erosion is the upstream extension of a valley through erosion at the valley head.
- Deltas: Deltas are fan-shaped deposits of sediment formed where a river enters a larger body of water.
- Meanders: Meanders are curved bends in a river’s course, formed by lateral erosion and deposition.
